The U.S. Department of Energy (DOE) has issued a final rule for the Energy Conservation Program: Energy Conservation Standards for Dehumidifiers that imposes more stringent energy standards on dehumidifiers as detailed below:
| Portable dehumidifier product capacity | Minimum integrated energy factor | |
|---|---|---|
| (pints/day) | (L/kWwh) | |
| 25.00 or less | 1.3 | |
| 25.01-50.00 | 1.6 | |
| 50.01 or more | 2.8 |
This effective date of the final rule is August 12, 2016, but compliance with the amended standards established for dehumidifiers is required on or after June 13, 2019.
